Effective immediately, complete mariner credential applications submitted to the National Maritime Center (NMC) are expected to be processed within four months from the date received.
The NMC has faced an extensive backlog of applications resulting from the 2026 lapse in appropriations. The recent timeline announcement marks substantial progress in reducing the wait time for mariners.
The new processing time of four months from the date received excludes any time waiting for mariner applicants to test or provide additional information. This improvement reflects expanded production efforts, overtime, surge processing, workflow efficiencies, and the reallocation of personnel and resources to reduce the backlog inventory accumulated during the lapse.
While application volumes remain elevated, current trends indicate continued progress toward restoring more normal processing timelines. Mariners and maritime employers should continue to plan accordingly and submit applications early to avoid potential disruptions to employment and vessel operations.
Key Information
Applications will continue to be processed on a first-in, first-out basis. Only applications demonstrating a clear and documented nexus to national defense will be considered for expedited processing.
Mariners are strongly encouraged to apply early via the ASAP Tool to account for unforeseen delays. As a reminder, mariner credential renewals may also be post-dated up to eight months, allowing mariners to renew early. Paper and incomplete submissions may delay issuance.
Mariners should verify the expiration dates on their medical certificates before submitting a renewal application. Medical certificate expiration dates may differ from MMC expiration dates, and medical certificate renewal may not yet be necessary.
